Glossary

Technical terms explained simply

a

Aerator

b

46f6a

Bayonet fitting

Fitting on the mixer tap shaft, which can be released by turning it in the opposite direction and slotting it into place and then reconnected, in order to lay the mixer tap on its side. This means windows can still be opened even if a mixer tap is installed underneath.

You will find this special feature in many of Kludi’s ranges of kitchen mixer taps.

Fitting that is screwed into the tap spout to ensure an even flow of water without splashing.

Adding air makes the jet of water softer and it saves on water consumption.

4022e

Flow rate class

Classification for mixer taps according to the water flow rate.

If the flow rate is too high, resources are wasted unnecessarily; if it is too low, it may have an adverse affect on convenience.

This is why standardised flow rates are a matter of course for brand-name mixer taps.The different flow rates are classed as follows:

Z: 7.5–9.0 litre/minute

A: 13.5–15.0 litre/minute

S: 18.0–19.8 litre/minute

B: 22.8–25.8 litre/minuteC: 27.8–30.0 litre/minute

D: 34.8–37.8 litre/minute

g

Grain of silica sand

The cavity (for the water flow paths) in a mixer tap is created with the help of a grain of silica sand. It is cast into a solid object using silica sand and components from resin and adhesive and is fired for a few seconds once the silica sand has been covered by the molten brass in the permanent mould.

4ca01

Hybrid mixer tap

Mixer tap that can be operated electronically or manually, such as the KLUDI E-GO.

j

Jet controller/flow limiter/aerator

Fitting that is screwed into the tap spout to ensure an even flow of water without splashing.

k

KTW approval

Components made of organic materials that are used in a mixer tap and come into contact with drinking water must have KTW approval (KTW = plastics in contact with drinking water) from the German environmental protection agency (Umweltbundesamt). Health and hygiene regulations are detailed in guidelines, e.g. for organic materials such as plastics, lubricants like valve lubricant or elastomers used in O-rings and gaskets.

Further requirements to protect drinking water from microorganisms on non-metallic materials are stipulated in the worksheet from the DVGW (DVGW = German Association for the Gas and Water Industry). Materials for seals have to comply with this technical standard, where the product is examined for its long-term microbiological behaviour in a material test. This ensures proof of these materials’ safety for use with drinking water, in particular avoidance of biofilms.

l

Lever

Operating element in a mixer tap for regulating the flow and temperature of the water.

ca4aa

Low-pressure mixer tap

Mixer tap for open-vented boilers (under-sink device).

Easily recognisable with the three hoses.

You will find low-pressure models in many of Kludi’s ranges.

There are high-pressure mixer taps as well as low-pressure taps.

m

The smallest thermostatic control mechanism in the world.

56de8

2cb36

Multi-connector

Connector and shut-off for washing machines and dishwashers in a sink mixer tap. This means that inconvenient pipe branches are no longer needed in the feed pipes. In 1968, Kludi was the first manufacturer to introduce this practical solution.

a6078

Multifunction mixer tap

Mixer tap for washbasins and sinks, such as those in the JOOP! range from Kludi, for example.

n

Noise class

Classification of mixer taps according to specific standards depending on how much noise they make.

All mixer taps used in multi-occupancy properties have to comply with DIN 4109 (sound insulation in buildings).

They are divided into two noise classes depending on the level of noise.

Noise class I: Emitted noise < 20 dB (A)

Noise class II: Emitted noise < 30 dB (A)

High-quality mixer taps are thus distinguished by their classification in noise class I. They have a built-in silencer to reduce noise levels. A “quiet” mixer tap can be identified by the P-IX... noise inspection symbol.

o

O-Ring

Sealing ring for two connectors.

3e8cc

Odour trap

An arched section of pipe that is filled with water, fitted in waste pipes to prevent sewage gases from escaping.

t

Tap hole

Hole for a mixer tap in a sanitaryware object.

ba3eb

Telescopic extension

Extension for the spout of a mixer tap, such as in one model in the KLUDI L-INE.

5f796

Test mark

The noise level of mixer taps must comply with the rules for sound insulation in buildings according to DIN 4109. The test mark on the mixer tap demonstrates that the accredited national test laboratories have performed the test in accordance with ISO 3822 and that the requirements have been met.

The code is made up of letters and numbers and gives the following information:

P = test certificate number

IX = specialist commission in Germany (building products)

1234 = registration numberI = noise class

S = flow rate class

5f574

Thermal disinfection

Method for eradicating Legionnaires’ disease (life-threatening bacteria) from plumbing in houses. To achieve this, the water heater needs to be operated so that the hot water flowing through the pipes still has a temperature of 70 °C. The risk of scalding should be taken into account, or it should be done at times when there is less consumption of hot water. To perform this effectively, hot water tapping points should be opened for at least 3 minutes. This helps to flush the pipe and the tap simultaneously, to disinfect them thermally and it kills the Legionnaires’ disease.
